So what can't you do with VMware's VSA?
I think it is a fair comment to say that its a step in the right direction for VMware in introducing a VSA but it looks like they have taken quite a large step of of the path. Their VSA has alot of limitations for $6k a server especially when you can only utilize 25% of the Server Storage and you still need a 3rd server as the Neutral Storage Host for vCentre etc.
I think considering there are a fair amount of Certified and non-certified solutions out there for VMware, end-users would have expected more bang for the buck.
Check out our VSA (StorMagic SvSAN) as an example of that althought only supporting 4.0 and 4.1 it has few limitations, currently undergoing VMware certification for availabilityy with vSphere 5 release.

HP Are not The only one
There's a lot more VSA solutions out there that are getting taken on by VMware. companies such as Datacore, Falconstor, Starwind and ourselves StorMagic.
It's harder to swallow for companies who have aligned themselves with VMware as Partners or Certified Partners who have had to jump through flaming hoops in order to pass VMwares Certification tests and theye'll have to do it again for vSphere 5.
It will be interesting to see what comes of it, currently there is a VMware online event http://vshow.on24.com/vshow/vmware2011/?l=en#home where you don;t see VMware getting alot of love for vSphere 5.
